Raymond Hernandez14 said:Hey there, I have a quick question...
So, I’ve got this need—and honestly, a bit of a craving—to hook up a second power supply to my rig. About a year back, I stumbled upon some kind of wiring diagram showing how to run two PSUs off a single motherboard so they both kick on at the exact same time. I remember seeing how certain wires needed to be bridged or jumped, but the specifics are totally slipping my mind right now...
If anyone happens to know where that schematic is hiding, I’d really appreciate it if you could drop a link here!!!
Thanks a million!!?!🙂🙂

Edward Peterson70 said:I’m asking because I heard the absolute limit for stability is around 3.3GHz for this chip.
Edward Peterson70 said:Are you basing that on what Taipanov said? 🙂
Do you actually believe a better motherboard would squeeze out more performance?

Daniel Nguyen3 said:In my humble opinion, things could have turned out even worse.
He could have easily gone with an EVGA Power Supply 👍
Edward Peterson70 said:I wouldn't wish that kind of total chaos on my worst enemy😁
Kyle Sanchez4 said:it's almost as if they were rigging the numbers at the local dealership🤣
Daniel Nguyen3 said:Fine, sure, the processor performs adequately enough, but everything else about this setup is 👎
the motherboard uses an NVIDIA nForce2 chipset 😂😂
Daniel Nguyen3 said:Yeah, that was a top-tier setup back in 2004.👍
By the way, they just shoved every single component they couldn't offload onto you...
Kyle Sanchez4 said:Are you actually serious right now?? 🤣 🤣
Kyle Sanchez4 said:is that an overclock or just the factory setting?
Edward Peterson70 said:you just bolt on a lawnmower engine, hop on the chassis, and tear off toward a LAN party😁

darkowl72 said:My e2200 was running at 280x11, which clocks in at 3.08GHz, with temperatures sitting at 76°C for TAT and 72°C during Orthos. I couldn't push it any further without messing with the voltage, and since what I had was perfectly sufficient, I didn't see much point in forcing the issue...
Now, I recall stumbling upon some discussion regarding undervolting—not in the sense of dropping the frequency just to cool things down or quiet the fans, but rather attempting to lower the CPU's clock voltage without sacrificing actual performance. Since I found myself with a bit of free time today, I figured I might as well see if it was worth the effort...
Working with an 11 multiplier yielded absolutely nothing... other than the realization that this processor is remarkably resistant to undervolting... 😉 At the default 1.45V, CPU-Z reports 1.45V and Drake 1.344V; at 1.43125V, it shows 1.392V and Drake 1.360V; then at 1.425V, it looks exactly the same (!)... and everything remains stable at 280x11 while the temperatures don't budge one bit... (?) It’s all a bit peculiar, but I kept going...
So, I decided to start playing around with the multiplier instead...
(A brief tangent: I previously established that cranking up the CPU voltage while keeping the multiplier at 11 doesn't allow the FSB to move even a single MHz past 280!)
Well, after a fair amount of tinkering and testing, I didn't manage to break anything 😉 and finally stumbled upon a winning combination:
410x8 = 3.28GHz, FSB = 1640
Voltages: BIOS is 1.44375V, CPU-Z shows 1.408V, Drake is 1.392 / 1.376V (mostly staying at the latter, though 1.392 pops up occasionally)
SPD = 2.0, RAM at 410 (1:1), latencies at 5-6-6-19 2T (Auto)
It’s holding steady under Orthos; it’s been over three hours now...
Temperatures
TAT at 66/66 and hasn't crossed a single degree higher
CoreTemp at 68/68
HWMonitor: tmpin0 48, tmpin1 63, core#0 68, core#1 68, GPU core 59, HDD0 45, HDD1 36
The cooler is a Thermaltake Blue Orb II, spinning happily at 1500 RPM (795 idle)
Motherboard is a P35-DS3, memory is 2x 2GB Kingmax 800, and the GPU is a Gainward Bliss 8800 GTS 320
As for why this dropped my load temperatures by a full 10 degrees (!), I honestly can't say whether it's due to the higher FSB paired with a lower multiplier, or perhaps a slight undervolt inherent to this specific configuration... I haven't the slightest clue, but the fact remains that the temperatures are much more reasonable now...
I should also point out the drive temperatures from startup compared to after about eight hours of runtime, even without heavy load:
Seagate BarraCuda 320, started at 30, now 45
Samsung T166 400, started at 24, now 36

It appears this processor simply refuses to cooperate with any frequencies north of 3.9GHz, regardless of how much voltage I throw at it. 😢
Though, we’ll see what happens in a day or two once the thermal paste actually settles in and does its job properly. 🙂
